The racism accusation is a little strong and isn't helpful to the debate. I do agree that the post you are referring to seems to be woefully devoid of any insight into the way the benefits that have accrued to the 'northern' economies and Germany in particular, from sharing a currency with Spain, Greece etc.
Maybe you should read up on the situation a little, instead of believing any old populist crap you read, because those comments border on racism.
